Effect of Vermicompost and Glomus versiform on control of Fusarium oxysporum f.sp. lycopersici on tomato plant

An experiment was conducted to determine the effect of Vermicompost and Glomus versiform, on tomato plant infected by of Fusarium oxysporum f.sp. lycopersici. Tomato seeds were sown in growth bed including: sterile soil (control), G. versiform (G), Vermicompost (V), Vermicompost Glomus (V). Five weeks later, the plant roots were dipped to F. oxysporum spore suspension as well as water and then transplanted. At the end of experiment, symptoms of disease (yellowing), morphological parameters, improvement of elements uptake, leaf chlorophyll and percentage of root colonization were assessed. Results showed that treatments with combination of Gand V were more effective on the above criteria than treating plants with single inoculations. Infected Plants by pathogenare treated with G significantly reduced yellowing incidence of leaves by17.30% and infected control treatment, 68.6% was estimated. Also regarding to the percentage of root colonization result, the effectiveness of dual application (Vᯡ) was proved by 23% increase. In the case of contamination by F. oxysporum fungi, the lowest amounts of chlorophyll were estimated in the control treatments with 12 (SPAD value), while it was increased in the (V) treatment (30). The highest uptake of N, P, K was recorded in V treatment. Based on these results, the application of combined treatments including G against this pathogen were found to ameliorate tomato plant growth and health, so they could be recommended for this disease.
